Can anyone please help?! I've done lots of dyeing with procion mx dyes, with good results. I have tried to use chocolate brown to help my daughter with a GCSE project. As soon as I mixed the dye with water I got the green and black elements seperating. No amount of mixing would fix the problem and the dyeing turned out to look like camoflage green/black and no brown in sight. Any hints of what is going wrong?
